Two kinds of macromolecules applied in papermaking were modified with β-cyclodextrin (β-CD) and loaded with ciprofloxacin hydrochloride (CipHCl) in an attempt to compare their potential applications in antimicrobial paper. β-CD grafted cellulose (β-CD-Cel) and β-CD grafted cationic starch (β-CD-CS) were prepared by grafting β-CD onto cellulose fiber and cationic starch using citric acid (CA) and epichlorohydrin (ECH) as crosslinking agents, respectively. β-CD-Cel and β-CD-CS were both loaded with an antimicrobial agent (CipHCl) to form inclusion complexes, namely β-CD-Cel-CipHCl and β-CD-CS-CipHCl. Furthermore, the inclusion complexes were added to the pulp to prepare antibacterial paper. The antimicrobial activity and physical properties of the paper were investigated. The results showed that the paper with both inclusion complexes exhibited excellent antibacterial activity, and the antibacterial activity with β-CD-CS-CipHCl was higher than that with β-CD-CelCipHCl. Moreover, the addition of both β-CD-Cel-CipHCl and β-CD-CSCipHCl affected the tensile and tear strengths of the paper. The paper with β-CD-CS-CipHCl had better physical properties than that with β-CDCel-CipHCl because the CS acts as a reinforcing agent in papermaking. These prepared antibacterial paper sheets may be useful for preventing wound and nosocomial infections in the medical and packaging fields.

“…Carboxymethyl cellulose (CMC) due to its viscosity, water binding properties and transparency solute is used mainly in food industry. Among the biopolymers, carboxymethyl cellulose is available in large quantities, process is done on it easily, is inexpensive and has excellent feature for film creation [10][11][12]. Cellulose and its modified forms are one of the composites of cellulose than can be dissolved in water and are flexible and firm by it.…”

“…One of the most important polysaccharides that are used in production of edible films is cellulose and its modified forms. Cellulose is the most accessible and frequent natural polymer that forms the most primitive structure of green plants [11,12]. Carboxymethyl cellulose (CMC) is water-soluble cellulose derivatives, and is used as a viscosity enhancer, condenser, water conservation agent, or used as a 2 of 7 bonding agent.…”

Using biodegradable films is increasingly growing since they contain natural materials. In this study, sago starch and carboxymethyl Cellulose (CMC) were used in film preparation. Sago starch films with 0, 5, 10, 15 and 20% CMC concentrations were prepared using solvent casting method. The mechanical properties were determined according to standards of American Society for Testing and Materials. In mechanical test of the combined films, increased CMC concentration significantly (P<0.05) increased tensile strength and Young Modulus from 21.04 to 27.74MPa and from 1372.83 to 1842.87kg/m2, respectively, and percent elongation showed significant (P<0.05) reduction from 17.69 to 15.39. Considering biodegradability of the edible films and improvement of their mechanical properties by CMC, they can be utilized in different industries, particularly in food industry, as an edible coating for packaging food and agricultural products. With regard to its properties such as cost saving, biodegradability and mechanical properties when percentage of CMC increased can found a position among food packaging materials.
